got but getting Mac OS X to run smoothly on VirtualBox or VMware very difficult...loading very slow, almost every things don't seem to work as it should on a Mac.
But if u got patience and the technical know-how, you can google Niresh Mavericks iso and try it out yourself...
Alternatively, you can try to build a Hackintosh PC by yourself, very easy to get it to work and it is the same as running a native iMac too.
u will get all the info required on tonymacx.com
